An off-duty firefighter was busted yesterday for driving while intoxicated after he crashed his car into another vehicle in Queens – just months after he was charged with assaulting his former building super.

Ahmed Morsi, assigned to Engine Co. 326 in Oakland Gardens, was charged with DWI after the smash-up in Astoria just after 3 a.m., police said.

The booze-fueled crash occurred when Morsi, 32, slammed his 1984 Saab into another car at Broadway and 42nd Street, cops said.

Both Morsi and the two occupants of the other car, a 1985 Mitsubishi, suffered minor injuries in the smash-up and were treated at Mt. Sinai Hospital.

Morsi’s DWI arrest is just the latest black eye for the FDNY, which has been reeling in the wake of several alcohol-fueled incidents, most notably the Staten Island firehouse attack that left one smoke-eater critically injured.

Morsi has been one of New York’s Bravest for nearly two years.

On Christmas Eve, Morsi was arrested for allegedly assaulting the super at 34-07 36th Ave. in Astoria.
